Introduction:
You have purchased the 4-fold decoder kit 1-DEC-DC for your
model railway supplied within the assortment of Littfinski
DatenTechnik (LDT). The 1-DEC-DC kit is a high quality product
which is easy to assemble.
We wish you having a good time to assemble and using this
product.
The 4-fold decoder 1-DEC-DC of the
Digital-Professional-
Series
can be used without any problems on your digital railway.
General:
Tools required for the assembly
Please assure that the following tools are available:
•
a small side cutter
•
a mini soldering iron with a small tip
•
solder tin (if possible 0,5mm diameter)
Safety Instructions
•
All electrical and electronic components included in this kit
shall be used on low voltage only by using a tested and
approved voltage transducer (transformer). All components
are sensitive to heat. During soldering the heat shall be applied
for a very short period only.
•
The soldering iron develops a heat up to 400°C. Please keep
continual attention to this tool. Keep sufficient distance to
combustible material. Use a heat resistant pad for this work.
•
This kit consist of small parts which can possibly be swallowed
from children. Children (especially under 3 years) shall not
participate on the assembly without supervision.
Set-Up:
For the board assembly please follow exact the sequence of the
below assembly list. Cross each line off as done after
completing the insertion and the soldering of the respective part.
For the diodes please keep special attention to the correct
polarity (marked line for the cathode).
With reason to different makes of electrolytic capacitors you
will find different markings of the polarity. Some are marked with
"+" and some are marked with "-". Each capacitor has to be
assembled to the board that the marking on the capacitor is in
correspondence with the marking on the pc-board.
Integrated circuits (ICs) are either marked with a half round
notch on one end or a printed point for the correct mounting
position. Push the ICs into the socket assuring that the notch or
the point is corresponding with the triangular marking on the pc-
board.
Please attend to the sensitivity of the IC´s to electrostatic
discharge, which will cause immediate damage of the IC. Before
touching those components please discharge yourself by
contacting an earthed metal (for example an earthed radiator) or
work with an electrostatic safety pad.
Please attend to the mark "+" of the rectifiers. Some
manufacturers mark the "+" connections additionally with a
longer connection wire. If the rectifier shows as marking a
flattened side this side has to correspond with the marking on the
pc-board.
For sufficient heat transfer the diodes D20 and D21 should not
be assembled directly to the pc-board but shall be soldered at a
distance of 5mm to the board.
